Interrupt number for SW2 and SW3 in the CC3200 LAUNCHXL

Hi Shaman,

Please take a look at the button interface source 'button_if.c' (cc3200-sdk\example\common). Here the interrupts are registered with the RTOS by using the wrapper 'osi_InterruptRegister'.

For SW3, the interrupt number 17 (INT_GPIOA1, GPIO port S1) is used. And for SW2, the interrupt number 18 (INT_GPIOA2, GPIO port S2) is used.

ok, now I have 70 warnings like:

#48-D incompatible redefinition of macro "Hwi_clearInterrupt" (declared at line 645 of "C:/ti/tirtos_simplelink_2_12_01_33/products/bios_6_41_04_54/packages/ti/sysbios/hal/Hwi.h") .ccsproject /SimpleProject line 1282, external location: C:\ti\tirtos_simplelink_2_12_01_33\products\bios_6_41_04_54\packages\ti\sysbios\family\arm\m3\Hwi.h

for every Hwi API basically.

what should I do?
Why is not enough to enable Hwi module and statically instantiate a Hwi function via the cfg file?
Am I missing something?

Hi Shaman,

What code base are you updating here? Is this from the CC3200 SDK? If yes, then please explain about the changes that you have made.

I have this:
CCS 6.1.0.00104
TI compiler 5.2.3
RTSC 2.12.1.33 with XDC tools versione 3.31.0.24_core

I create a new CCS project, choose template > TI-RTOS example > Driver example > CC3200-LAUNCHXL > example projects > minimal footprint

from the created files, I rename empty.cfg in app.cfg, empty.c in main.c
then I used PinMux to create the mux_config.h and .c files that enables the PIN for 3 LED and 2 SWITCH buttons.
and I replaced those made by the template.

then I edited CC3200_LP.h by uncommenting the enum values for CC3200_LP_LED_D5 and D6 in the typedef "CC3200_LP_GPIOName", because they are disbled by the generated files.
Also in board.h I put the
#define Board_LED1 CC3200_LP_LED6
#define Board_LED2 CC3200_LP_LED5


then I created 3 task instance in the cfg file.
I created 3 functions in the main.c that are called each by each task.

the code for the task is simply this:

Void task_led0(UArg arg0, UArg arg1)
{
while (1) {
Task_sleep((UInt)arg0); // arg0 = 1000 in the cfg file
GPIO_toggle(Board_LED0);
}
}

Void task_led1(UArg arg0, UArg arg1)
{
while (1) {
Task_sleep((UInt)arg0); // arg0 = 2000 in the cfg file
GPIO_toggle(Board_LED1);
}
}

Void task_led2(UArg arg0, UArg arg1)
{
while (1) {
Task_sleep((UInt)arg0); // arg0 = 4000 in the cfg file.
GPIO_toggle(Board_LED2);
}
}


IT WORKS.

BUT

now I want to create Hwi, and toggle LED by button switch, in Hwi context

I want a function:


Void hwi_led0(UArg arg0)
{
GPIO_toggle(Board_LED0);
}

to be executed in Hwi CONTEXT

so I enabled Hwi MODULE in cfg file
instance -> add -> hwi0
that calls hwi_led0 function, interrupt number 17 (for the button) (the number you gave me previously).

It compiles with warnings, 70 warnings, complaining that there are redefinition of defines (see previous message)

I found that there are 2 defines, for every Hwi API

this:

#define     Hwi_create      ti_sysbios_hal_Hwi_create

is in the ...\Hal\Hwi.h

but there is another define, generated by the XDC tools (or RTSC I don't know.... the tool that processes the cfg file):

#define    Hwi_create       ti_sysbios_family_arm_m3_Hwi_create

that appear in ...\Family\Arm\M3\Hwi.h

I found that the generated file : "app_pem4.c" has:

#include <ti/sysbios/family/arm/m3/Hwi.h>

and also , a few lines underneath:

#include <ti/sysbios/hal/Hwi.h>

that is causing 70 warning.

how can I fix it?

Moving this thread to TI-RTOS forum, as it is specific to the build errors in the TI-RTOS example.

That example doesnt' use Hwi, it uses callbacks

In fact if you look into the cfg file, there is nothing on the Hwi instance.

Also in code, no lines of Hwi_create
